Water-based coatings: "A lot of new binder technologies"
Water-borne coatings contain a lot of water and therefore the layer thickness and filling of the surface are not always up to requirements. The new binder systems increase the solids content of the formulation and, in combination with rheology control, can bring improvements in the direction of the desired performance.

Bentonite Use In Coatings – Polymeraddcoth
Bentonite acts as a rheological modifier in coatings, helping to control viscosity and improve flow properties. When dispersed in water or solvent-based coating formulations, bentonite forms a thixotropic gel structure, which prevents settling of pigments and fillers, enhances sag resistance, and ensures uniform application of the coating.
